With just two swings of the bat, the Colorado Rockies sent the San Francisco Giants to another loss.

Carlos Gonzalez and Nolan Arenado hit back -to-back home runs in the bottom of the first inning off of Chris Heston, as the Rockies defeated the Giants 2-1 at Coors Field.

It is the seventh straight loss for the struggling Giants.

Gonzalez continues to stay hot, as he has five home runs in his last three games. Arenado has a home run in five straight games.

The Giants got within one run in the top of the sixth inning, when Angel Pagan singled. Matt Duffy then singled, then Buster Posey was hit by a pitch. Jorge De La Rosa got out of the jam, as he struck out Marlon Byrd.

De La Rosa did not walk a batter and struck out seven in seven innings of work.

Closer John Axford picked up his 19th save, as he got Brandon Crawford to ground into a double play to end the game.

Heston went 5.2 innings, allowing two runs on seven hits.
